Tank Heating

Hello All:
I have a cooling tank which is used to cool higher chain hydrocarbons from 400 Deg C to around 250 Deg C. To avoid material solidification inside the tank there is an immersion heater but the heating is only accomplished up to level of the heater. To avoid material solidification at the bottom of the tank; I'm thinking of wrapping mineral insulated cable on the bottom to provide heat.
Any thoughts or recommendations over using MI cable? any other advice based on prior experience
Regards,

Place a sheet metal baffle around the heater inside the tank. The baffle can form a chimney around the heater with a gap of a couple inches from the tank floor. That way hot fluid rising from the heater will draw-in cold fluid from the tank floor.

The construction I have seen (although for lower temperatures) is tanks with mixer and a combined outer shell (or envolving spiral) for heating steam and cooling water (one or the other alternatively).
